Acute respiratory failure secondary to COVID-19 pneumonia may require a variety of non-pharmacological strategies in addition to oxygen therapy to avoid endotracheal intubation. The response to all these strategies, which include high nasal flow, continuous positive pressure, non-invasive ventilation, or even prone positioning in awake patients, can be highly variable depending on the predominant phenotypic involvement. Deciding when to replace conventional oxygen therapy with non-invasive respiratory support, which to choose, the role of combined methods, definitions, and attitudes toward treatment failure, and improved case improvement procedures are directly relevant clinical questions for the daily care of critically ill COVID-19 patients. The experience accumulated after more than a year of the pandemic should lead to developing recommendations that give answers to all these questions.

Background: In 2018, nocturia and nocturnal lower urinary tract function definitions were updated in a clinically and practically based consensus report by the International Continence Society Standardization Steering Committee. Previous research has suggested that the pathophysiology of nocturia has a multifactorial etiology, including obstructive sleep apnea, overactive bladder syndrome, diabetes mellitus, sleep disturbance, congestive heart failure, primary polydipsia, and other factors.Current Concepts: Three main mechanisms have been identified: low functional bladder capacity, nocturnal polyuria, and diurnal polyuria (24-hour polyuria). Multifactorial pathophysiology implies multiple possible targets for therapeutic intervention, and suggests that it is unlikely that one treatment modality, including drugs, will be successful in all patients. The bladder diary is the most important diagnostic tool.Discussion and Conclusion: Strong evidence supports the efficacy of desmopressin and continuous positive pressure breathing. Antimuscarinic drugs for treating nocturia display limited usefulness because of their low efficacy for nocturnal polyuria. Management of nocturia may require a multidisciplinary approach to visualization and phenotyping of patients for diagnosis and therapy.

Introduction The impact of sleep disordered breathing (SDB) on arterial intima-media thickness (IMT), a surrogate measure for cardiovascular disease, remains uncertain, in part because of the potential for non-SDB vascular risk factor interactions. In the present study, we determined predictors for common carotid (CCA) and femoral (CFA) artery IMT in an adult, sleep clinic cohort where non-SDB vascular risk factors (particularly diabetes) were eliminated or controlled. Methods We recruited 296 participants for polysomnography (standard SDB severity metrics) and CCA/CFA ultrasound examinations, followed by a 12 month vascular risk factor minimisation (RFM) and continuous positive pressure (CPAP) intervention for participants with a range of SDB severity (RFM Sub-Group, n = 157; apnea hyponea index [AHI]: 14.7 (7.2–33.2), median [IQR]). Univariable and multivariable linear regression models determined independent predictors for IMT. Linear mixed effects modelling determined independent predictors for IMT change across the intervention study. P<0.05 was considered significant. Results Age, systolic blood pressure and waist:hip ratio were identified as non-SDB predictive factors for CCA IMT and age, weight and total cholesterol:HDL ratio for CFA IMT. No SDB severity metric emerged as an independent predictor for either CCA or CFA IMT, except in the RFM Sub-Group, where a 2-fold increase in AHI predicted a 2.4% increase in CFA IMT. Across the intervention study, CCA IMT decreased in those who lost weight, but there was no CPAP use interaction. CFA IMT, however, decreased by 12.9% (95%CI 6.8, 18.7%, p = 0.001) in those participants who both lost weight and used CPAP > = 4hours/night. Conclusion We conclude that SDB severity has little impact on CCA IMT values when non-SDB vascular risk factors are minimised or not present. This is the first study, however, to suggest a potential linkage between SDB severity and CFA IMT values.

Background: Ehlers-Danlos Syndromes (EDS) and Hypermobility Spectrum Disorders (HSD) are a heterogeneous group of heritable genetic connective tissue disorders with multiple characteristics including joint hypermobility, tissue fragility, and multiple organ dysfunction. Respiratory manifestations have been described in EDS patients, but have not been systematically characterized. A narrative review was undertaken to describe the respiratory presentations and management strategies of individuals with EDS and HSD. Methods: A broad literature search of Medline, Embase, Cochrane Database of Systematic Reviews, and Cochrane CENTRAL was undertaken from inception to November 2020 of all study types, evaluating EDS/ HSD and pulmonary conditions. This narrative review was limited to adult patients and publications in English. Results: Respiratory manifestations have generally been described in hypermobile EDS (hEDS), classical and vascular EDS subtypes. Depending on EDS subtype, they may include but are not limited to dyspnea, dysphonia, asthma, sleep apnea, and reduced respiratory muscle function, with hemothorax and pneumothorax often observed with vascular EDS. Respiratory manifestations in HSD have been less frequently characterized in the literature, but exertional dyspnea is the more common symptom described. Respiratory symptoms in EDS can have an adverse impact on quality of life. The respiratory management of EDS patients has followed standard approaches with thoracotomy tubes and pleurodesis for pleural manifestations, vocal cord strengthening exercises, continuous positive pressure support for sleep apnea, and exercise training. Reduced respiratory muscle function in hEDS patients responds to inspiratory muscle training. Conclusion: Respiratory symptoms and manifestations are described in EDS and HSD, and have generally been managed using conservative non-surgical strategies. Research into the prevalence, incidence and specific respiratory management strategies in EDS and HSD is needed to mitigate some of the associated morbidity.

Objective: To analyze the clinical effect of nasal continuous positive airway pressure (CPAP) combined with pulmonary surfactant in the treatment of neonatal respiratory distress syndrome (NRDS). Methods: Eighty-two NRDS patients who received treatment from August 2017 to June 2019 in our hospital were selected and divided into a control group and an observation group using random number table, 41 in each group. The control group was treated with CPAP, and the observation group was treated with pulmonary surfactant injection besides CPAP. The therapeutic effect, blood gas index, mechanical ventilation parameters and occurrence of complications were compared between the two groups. Results: The total response rate of the observation group was 90.24%, which was significantly higher than 70.73% of the control group, and the difference had statistical significance (P<0.05). After treatment, the improvement of blood gas indexes of the observation group was better than that of the control group. The hospitalization time and duration of oxygen treatment of the observation group were shorter than those of the control group, and the hospitalization cost was higher than the control group (P<0.05). The difference of incidence of complications between the two groups was statistically significant (P<0.05). Conclusion: Endotracheal injection of pulmonary surfactant combined with CPAP in the treatment of NRDS can enhance the efficacy, promote the recovery of blood gas index, and reduce the parameters of mechanical ventilation and the incidence of complications, which is conducive to improving the respiratory function of the newborn. The therapy is worth application in the treatment of NRDS patients. doi: https://doi.org/10.12669/pjms.36.4.1963 How to cite this:Miao J, Xie H, Zhang Y, Guo X, Cui M.
